Technical field
The present invention relates to a kind of bevel for welding surface finish technology, particularly a kind of bevel for welding sanding apparatus.
Background technology
The pressure vessel main weld needs processings of polishing of impurity such as the iron oxide, iron rust to groove face before welding, with assurance welding procedure quality requirement.But present polishing process is to adopt manual grinder buffing, because the difference of operative employee's technical merit, it is not thorough that iron oxide and iron rust are handled, and efficient is lower.
Summary of the invention
For solving the problems referred to above that prior art exists, the objective of the invention is to design a kind of bevel for welding sanding apparatus and polishing process thereof that quality is good, grinding efficiency is high of polishing.
To achieve these goals; Technical scheme of the present invention is following: a kind of bevel for welding sanding apparatus comprises small-sized manipulator, sanding apparatus and control cabinet; Described small-sized manipulator comprises lifting motor, column, slide plate, crossbeam, base and crossbeam drive motors; Described column is fixed on the base; Described crossbeam is installed on the cross slide way of slide plate through first directive wheel and first bogie wheel, first bogie wheel can be along the cross slide way move left and right on the crossbeam, and described slide plate is installed on the longitudinal rail of column through second bogie wheel and second directive wheel, and second bogie wheel can move up and down along the longitudinal rail on the column; Top, its axle that described lifting motor is installed in column are connected with sprocket wheel; The one end engagement of described sprocket wheel and chain, the other end of chain is connected with slide plate, and described crossbeam drive motors is installed in the left end of crossbeam; Described sanding apparatus comprises cross bar, abrasive band drive motors, abrasive band active wheel, V-belt, screw mandrel lowering or hoisting gear, fixture and abrasive band regulating wheel; Described abrasive band drive motors, abrasive band active wheel, abrasive band regulating wheel are installed on the cross bar respectively; Described cross bar fixes on the fixture through hinges fixing; The structure of described fixture is " L " type structure, is fixed on the crossbeam front end with set bolt; Described screw mandrel lowering or hoisting gear top is connected with cross bar, the bottom is connected with fixture; Described abrasive band drive motors is connected with the belt pulley of active wheel bottom, abrasive band through belt pulley and V-belt, described control cabinet be fixed by bolts to column rear side, pass through cable and be connected with lifting motor, crossbeam drive motors, screw mandrel lowering or hoisting gear and abrasive band drive motors respectively.
On the sanding apparatus of the present invention guard shield is installed.
A kind of polishing process of bevel for welding sanding apparatus may further comprise the steps:
A, workpiece is installed on the carrying roller, and with the whole handling of bevel for welding sanding apparatus to the buffing work-piece place, and preliminary aligned position, energized;
B, press the up-down adjustment knob on the control cabinet, start that lifting motor drives slide plate and crossbeam moves up and down, make the height of abrasive band active wheel consistent with the workpiece grooves height;
C, press the left and right adjusting knob on the control cabinet, start the crossbeam drive motors and drive the crossbeam move left and right, make the abrasive band active wheel near workpiece welding groove;
Handwheel on D, the adjusting screw mandrel lowering or hoisting gear makes the angle of abrasive band active wheel consistent with the workpiece welding groove angle;
E, startup carrying roller make the workpiece rotation, start the abrasive band drive motors and make abrasive band active wheel rotation, start the crossbeam drive motors and make abrasive band active wheel contact workpiece groove, can realize the automatically grinding of bevel for welding.
Compared with prior art, the present invention has following beneficial effect:
1, because the present invention can make crossbeam carry out the bite of move left and right when controlling the polishing of abrasive band active wheel through the crossbeam drive motors; Can adjust the grinding angle of abrasive band active wheel simultaneously through the handwheel on the adjusting screw mandrel lowering or hoisting gear; Bite and the uneven shortcoming of polishing when having overcome artificial polishing fully, thus the polishing quality of bevel for welding improved.
2, be 5.5 meters for diameter of work, bevel for welding thickness is 300 millimeters workpiece, if adopt artificial polishing, three people polish simultaneously and need 4-5 hour.Because abrasive band of the present invention active wheel width is 100 millimeters, the width of therefore each polishing bevel for welding also is 100 millimeters, and the linear velocity in abrasive band is 40 meter per seconds, and the rotating speed of carrying roller is 1 meter/minute, with the present invention's bevel for welding of polishing, only needs 51 minutes.Therefore improved grinding efficiency greatly.
